Land Doctrine Guide 2024 - Hearts of Iron IV 

In summary: Superior Firepower - Integrated Support - Shock & Awe is the default. SF - Integrated - AirLand if you want to do a little bit of tanks, but not too much. SF - Dispersed - Shock & Awe if you wanna do city sieges specifically. SF - Dispersed - AirLand don't. Mobile Warfare - Mobile Infantry if you wanna do mechanized spam (O Canada...) Mobile Warfare - Blitzkrieg if you wanna do tank spam. Don't ever take Desperate. Don't do Grand Battleplan unless you've specifically got the job to HOLD THE LINE. Mass Assault - Deep Battle for shit terrain fighting. Mass Assault - Mass Mobilization for meming on Japan.

I'd say the max planning from Grand Battleplan can actually be quite amazing. The issue is, in a lot of wars, the first week or so is the most critical time. This is when each side has the most entrenchment and planning, and therefore the highest stats on both offense and defense. It's also typically when each side has full strength, fully trained divisions. If GBP gives you both more entrenchment and more planning, then it can be possible to weather the storm from the enemy if they attack, then counterattack with something like a 90-100% planning bonus. One of the biggest advantages of planning bonuses over direct soft attack bonuses, is that planning boosts not only soft and hard attack, but also breakthrough. An extra 10% planning is as good as an extra 10% soft attack, hard attack, and breakthrough put together. The planning bonus may take a while to build up, but it also takes awhile to lose when a division is on the line. I believe typically you'll lose 2% planning per day when a division is moving or defending an attack. That means that, if you start a war with 90% planning, you can get 20-25 days of good planning bonus, which may be enough to roll back the line 4 tiles deep, destroying something like 40% of the enemy's deployed equipment. If they don't have additional stockpiles, then even without planning, they will not be surviving the rest of the war. Also, the land night attack bonus can be very good. -50% night attack usually means nothing happens during the 12 hours of night, but -25% allows you to do decent damage during the night. It might be about as good as a 7.5-12.5% soft+hard attack bonus. Depending on how much you rely on overpowering enemy divisions vs just grinding them down. By the way, I consider organization bonuses to generally not be that good. It makes your divisions last longer in battles, yes, but you divisions don't gain any hp, and don't deal any more damage. If I could swap out every +10 org bonus for a +10% attack bonus, I absolutely would. Even at the cost of maybe losing some battles, dealing more damage to enemy strength wins more in the long term.

I always felt like superior firepower was the go-to single player doctrine. Make loads of cheap soft attack infantry divisions, put the rest on planes, and just battleplan away. I feel like the AI isn't good enough to justify making cracked out tank divisions but it is entertaining to do that sometimes for fun.

In testing actual combats, land night attack is among the most impactful unlocks in any doctrine tree, period. Only exception is if you have enough juice to win fights during a single daylight period...not a scenario where you'd need much help from doctrines. What really holds GB back in MP is the horrible implementation of espionage, where 5 nations with 20% spy network completely remove planning. Were it not for that, you could do things like staff office plan and invest in command power generation to keep planning relatively high. Since the enemy can completely strip it with very little counterplay, however, the utility is limited. If trading expeditionary forces to stack some non-GB doctrine benefits onto planning/entrenchment of GB is allowed, this is a doctrine EVERY faction should have on some of its members though. Superior firepower divisions are pretty good. SF divisions receiving GB max planning are better. Mass mob guerilla tactics rolls + huge reinforce rate can be miserable to deal with. You need fewer units to maintain a rotating defense on front line, by a lot. If the support companies can do at least some damage to attackers or the nation who has it is using CAS, it can start changing the outcome of the game. It's non-trivial to beat guerilla w/o putting howitzers on tanks, and that makes said tank divisions much worse vs other tank divs.

Would be based if you did this for air and naval doctrines too

Meta nerds crying that GBP isn’t being glazed like it’s not the slowest, most micro intensive, least forgiving option that gets majority of its benefits completely countered by a single spy that you have no means of effectively getting rid of.

Bad "guide" trying to pass myths and personal opinions as facts. GBP left side is king of offense. SF if you want your naval invasions to land. Left/Left Mobile Warfare for small nations lacking manpower for that AWESOME defensive tactic "guerrilla warfare" (seriously, try it)

HOI4 Guide try not to be objectively wrong challenge : Impossible

How do you explain the default meta for MULTIPLAYER mind you, not singleplayer where literally everything works, to be GBP assault if tanks and Mass Mob if you are going for an infantry nation? I don't mean to diss this guide, but to say there is always a back and forth in the eastern front where you can't get max planning is false, it is a huge ass front and unless you battleplan like a bot you will have units on the frontline (tanks specially) building planning and reaching the levels of soft and hard attack (1.5k+) needed to break river lines and your opponent tanks that will have 1.5k+ stats from defensive terrain buffs alone. Superior Firepower for example is great on paper, but it gets outstated by planning every single time, the buffs you get are negated by pretty much any negative modifier you can get, mobile warfare is good because you can have decent planning while also having such high org on your tanks that you can have less mechanized in the template and reach a ton of stats, but still get outstatted by gbp. I mean i really appreciate guides, specially those that aim to teach multiplayer as that can be gatekeeped to hell by most players and the only real way to learn is getting shit on and trying again while analysing saves, but also spreading info like this is just going to get people that think they know the meta, to get shit on the exact same and have a "but muh guide" button to be stubborn.

good for single player but in mp just do gdp left or mass mob right

So I will say that this guide isnt remotely accurate from the beginning. For mobile warfare you can go to desperate defense to bank the manpower and then switch over to the doctrine with your banked manpower which is how most multiplayers running MW are running it. Grand Battle Plan is actually one of the stronger doctrines because it helps you absorb the initial punch which is when the opponents best units are attacking. Additionally, you even stated it yourself that the frontlines move back and forth and you are right which is EXACTLY WHY 50% entrenchment speed is huge. Additionally, you get a spirit which reduces all supply consumption for air, land, and sea by 5% which adds up

full blast i could hardly hear you, nice video tho

Left doctrines are offensive, right doctrines are defensive

Thank you general

I love going on youtube and looking an the complete lack of knowledge about this game, yet confidence to post trash videos like this which will mislead newer players

Well this is a voice I haven't heard in a while.

This guide is cooked. Org and soft attack bonuses don’t compare well too good planning

superior firepower as soviets is so strong tho

Very bad video, you dont understand game mechanics. GBP is the strongest doctrine, you need the entrenchment so you can push with your high planning elsewhere. It helps create a big breakthrough to start pushing agressively.
